Answering to the point of fungibility (i’ve just read again the net’s description).
Why would the proposed money of the living beings suffer the same inflation as the money of institutions, and the same inflation of the money for machines? You’ve got a point there, but not against the proposal, seems to be the opposite.
Scarcity establishes the value of things (through supply and demand in the market), even the value of money. But if the amount of living-conscious-physical-beings grows at a certain rate, and the other types of entities (institutions, machines, robots, AI’s, devices, etc) grow at a different rate… why should living entities suffer the inflation rates generated by the other ones?
This appears to lead again to the question of “who serves who?”. Seems difficult to find a reason for life to serve non-living entities.
I firmly believe the main reason of the existence of this Universe is the expansion of life. Under this precept, this is not the right Universe for living conscious entities to serve the others types.
